評論了真空击穿的理論及試驗情况。在极間距离为0.015时情况下进行的測量表明,在管內压强約10~(-5)～10~(-7)乇及所加电压頻率在0～6兆赫之間击穿无变化或很少变化。改变电极材料、几何形状及表面处理沒有提供显著的改进,但高压老炼或处理改善击穿特性1～2倍。阴极表面鬚形突出所增高的場致发射,致使場发射的預击穿电流的个別注流从阴极流向阳极。預击穿的电流,能使突出部分发生电阻加热及局部的电子轰击阳极加热,两者所产生的蒸发及毁坏效应能导致击穿。
Comments on the theory of vacuum breakdown and experimental conditions. Measurements made at a pole-to-pole distance of 0.015 show that there is no change in breakdown at about 10 -5 Torr to about 10 -7 torr and an applied voltage frequency between 0 and 6 MHz Little change. Changing the electrode material, geometry, and surface treatment did not provide significant improvement, but high pressure aging or treatment improved the breakdown characteristics 1 to 2 times. The cathode surface is shaped to protrude the increased field emission, causing the individual injected currents of the pre-firing current of the field emission to flow from the cathode to the anode. Pre-break through the current, make prominent part of the resistance heating and local electron bombardment anode heating, the evaporation and the destruction of both the effect can lead to breakdown.
